Credit Score Interest Rate

Question: What type of interest rate would a 638 Credit Score get?
For a new home purchase that is...
I have well over the 20% down, for like 35%. Also, I currently have a mortgage on my current home but want to sell and buy bigger.
Looking at a 350,000 home with 110-120K down
Answer: I'm not sure if anyone here is qualified to tell you, however my sister whose Credit Score is 618, due to being a single mother, just qualified in our state for a mortgage with 5.25%, and NO money down, so don't listen to all naysayers, you do not need perfect credit, she has a bankruptcy from 2004 on hers.
